As part of NASA’s Earth Right Now campaign, the space agency encouraged people globally to take selfies and post them to any one of several social media sites using the hashtag #GlobalSelfie.

“On this Earth Day, we wanted to create a different picture of our planet — a crowd-sourced collection of snapshots of the people of Earth that we could use to create one unique mosaic of the Blue Marble,” NASA said.

The final #GlobalSelfie mosaic, as well as a video using the images, will be released in May after capturing photos posted to Twitter, Instagram, Facebook, Google+, and Flickr.

As of Tuesday afternoon, NASA had received thousands of pictures via social media, spanning from Kansas City, Mo., to Baghdad, Iraq, to Antarctica. Here are just a few of them.
